I have been attempting to set up Thunderbird from a default install of Ubuntu 12.04LTS Desktop. Attempting to click on the inbox gives:
The current operation on Inbox did not succeed. The mail server for account blah@gmail.com responded: System error(Failure)
I've also changed the servers to imap.gmail.com from imap.googlemail.com, but to no avail. I see my folders, but I can't see inside them. I've also enabled smtp, pop, and imap from the google account settings side from within the web client.
Any ideas?
In the meantime, you can login to Gmail through your phone or tablet's browser. For iOS users, you can also download the Gmail application as an alternative in the interim." On this page http://support.google.com/mail/bin/static.py?hl=en&page=known_issues.cs
